Unlike lactic acid that has a smaller molecule or glycolic acid, which is even smaller, mandelic acid has something special going for it in regard to benefits for skin. Besides being kinder to the skin with less redness and irritation, this acid that comes from bitter almonds also has the ability to help counteract hyperpigmentation, mainly melasma because of how its molecule can block melanin production, despite its large size.
Mandelic acid performs in the same way that other alpha hydroxy acids and beta hydroxy acids exfoliate for cell turnover by loosening the structure of skin cells to bring them to the surface and encourage fresh ones to emerge. For your complexion, this can mean brighter skin with fewer chances of redness and that dryness and peeling that you may experience from daily use of a glycolic acid, lactic acid or salicylic acid.
In addition to the promise mandelic acid shows for aging as well as sun damaged skin, its skincare benefits extend to those suffering from acne or excessively oily complexions. Apparently, this acid also has antibacterial properties and the power to limit sebum production.
Even better news about mandelic acid benefits for skin is that it is suitable for basically all skin types. Just as importantly, it also can be used daily at low percentages without fear that you are overdoing those efforts for acne or anti-aging.
However, if your goal is anti-aging and getting rid of the look of those lines and wrinkles, there is something to keep in mind. Mandelic acid is better thought of for the difference it can make to improve hyperpigmention and the look of melasma over skin renewal such as glycolic or lactic acid.
While mandelic acid may not be perfect for benefits for the skin of all of us, it is another helpful advance toward beautiful skin.
